Chromosome | 6 | NCBI Gene Number | 16493 |
Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables voltage-gated potassium channel activity. Acts upstream of or within Notch signaling pathway; regulation of membrane potential; and regulation of vasoconstriction. Located in intercalated disc and plasma membrane. Is expressed in several structures, including gut; heart; metanephros; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in familial atrial fibrillation and pulmonary hypertension. Orthologous to human KCNA5 (potassium voltage-gated channel subfamily A member 5). PHENOTYPE: Mice homozygous for a knock-out allele exhibit abnormal microglial proliferation and nitric oxide release after LPS treatment or facial nerve lesion. Mice homozygous for a knock-in allele exhibit impaired hypoxic pulmonary vasoconstriction, and resistance to drug-induced cardiac QT prolongation. [provided by MGI curators] |
